Question

How does the debrogli wavelength for proton and neutron are equal?

Answer 1

Another name for the de-broglie wavelength is the matter wave

its relations show that the wavelenght is inversely prportional to the momentum of a particle... also the frequency of the matter waves is directly prortional to the total energy

of a particle

λ =h/p

λ=h/mv

v=h/mλ

Kinetic energy = 1/2*mv2

Substituting, K.E = 1/2*h2/mλ2

as we can see, K.E ∝ 1/m

mass of proton = 1.6726 x 10-27 kg

mass of neutron = 1.6749 x 10-27 kg

Therefore, since a proton has a lighter mass, it will have a higher value of kinetic energy.

Answer 2

Answer:

a proton is a lighter mass, it will have higher value than kinetic energy
